At Case Western University a quadriplegic man was able to move his right arm. Electrodes arrays were implanted to read signals from his motor cortex of his brain. The patient’s thought to move his hand and a computer analyzed it and helped him move the muscles in his arm. The patient first had to learn to move a graphical arm on a computer screen. This took several months of practice. Furthermore, his own muscles were atrophied from disuse. He needed weeks of physical therapy. Now the man can move his right arm enough to do simple basic tasks. This proof of concept was recently published in the Lancet. There is still much progress to be made. The electrodes are still very bulky and wires are sticking out from everywhere. This progress is a monumental step in getting mobility for those that are paralyzed. The technology still has a long way to go in terms of being smaller, being more affordable and being easier to use.
